Notes to Editors:

CarieScan PROtm

The PROtm is a highly accurate, easy to use, hand held device for the early detection and monitoring of dental caries (tooth decay). The PROtm already has CE Mark and FDA 510K approval for sale in Europe and the USA.

The CarieScan PROtm measures the presence of tooth decay earlier and more accurately than any other device on the market and is more than 90% accurate in detecting both sound and carious teeth, well ahead of other methods. It detects "hidden" decay, providing dental practitioners with the opportunity to arrest or even reverse decay, driving the trend towards preventative dental care.

The lightweight caries detection monitor not only offers best-in-class performance for decay detection but also allows easy monitoring of the effect of treatment regimes to show decay advancement or regression, thus enabling dentists to tailor treatment to the needs of the patient at a low cost. The CarieScan PROtm consists of a hand piece and a disposable sensor which is held against the tooth being examined in a process which takes approximately 4 seconds per tooth with the result displayed on the CarieScan PROtm.
